Red sex links have many names. Red sex link, red stars, gold sex link, gold comets, cinnamon queens and the list goes on. They all have either a rhode island red or a new hampshire red for the fathers but the mothers are all different breeds. The female chicks will be red with either white or black underfeathers and the males will all be almost entirely white. If you breed a sex link to a sex link you will not get sex links. You will get nice chickens that lay well but they will not be color sexable at time of hatch and throughout their lives.
The birds you have there that look like the one pictured are female sex links. Awesome layers and they will lay a large brown egg. They are pretty hardy in cold and heat as well.
